Introduction The testing of stressors and the impact of stress on health and work ability of electricians working in workplaces with a special health risk is very important.

OBJECTIVE is to examine the impact of occupational stress on the ability of electricians to work.

METHODS The research was designed as a cross sectional study and covered 108 respondents, classified into two groups: electricians (52) and control group (56) made up of administrative workers. The survey included the following: Questionnaire on basic sociodemographic indicators of respondents, IRS Questionnaire, Work Ability Index (WAI) Questionnaire, General Health Questionnsire (GHQ), Copenhagen Burnout Inventory (CBI) and Occupational Stress Assessment Questionnaire. Data analysis was performed with SPSS.

RESULTS The frequency of different categories of WAI score is uniform between the tested groups (p = 0.155). Work ability is poor in 11.5%, moderate in 25%, good in 26.90% and excellent in 36.5% of electricians. The frequency of different categories of WAI score is aligned between the tested groups (p = 0.155). By analyzing all components of IRS score, it was found that there is a statistically significant difference in the components between the electricians and the  control group: requirements (p <0.001) and work role (p <0.001); GHQ is higher in electricians, but no statistically significant difference was found (p = 0.082); CBI is statistically significantly higher in electricians (p <0.001) and WAI score is statistically significantly higher in electricians (p = 0.039). In the overall population, the 10 strongest stressors were ranked and statistically significant difference in all stressors (p <0.001) between the electrician and the control group was shown. The values of the stressors are equal in relation to WAI score categories. In the electricians, the strongest stressors are: night work (4.60), hazards (4.58), shift work (4.54), working overtime (4.46), time limit for individual tasks (4.44), fear of injuries (4.42), pressure of time limits for execution of tasks (4.23), work overload (4.22), inadequate work space (4.18) and daily unforeseen situations (4.10). Average value of all stressors among electricians is 2.87 ± 1.10 (Min 1.10, Max 4.60). In the tested population, 14 different stressors have higher values than the average value of all stressors. In the control group, the average value of all stressors is 1.84 ± 0.33 (Min. 1.17, Max 2.69). Correlation analysis has shown that there is a correlation of age with shift work (r = 0.130, p = 0.013) and working overtime (r = -0.220, p <0.001). URS is statistically significantly related to the time limit for individual tasks (r = 0.149, p = 0.005) and pressure of time limits for execution of tasks (r = 0.125, p = 0.017). ERS is statistically significantly related to night work (r = 0.169, p = 0.001), shift work (r = 0.160, p = 0.002), time limit for execution of tasks (r = 0.203, p <0.001) pressure of time limits for execution of tasks (r = 0.194, p <0.001), work overload (r = 0.128, p = 0.017) and inadequate work space (r = 0.122, p = 0.022). The subjective assessment of work ability in relation to physical (p = 0.010) and psychological requirements (p <0.001) is statistically significantly lower in electricians compared to control group. DISCUSSION By analyzing all components of IRS score, it is found that there is a statistically significant difference between the electricians and the control group in the requirements and the working role components. In the overall population, the top 10 stressors were ranked and it was shown that there was a statistically significant difference in all stressors between the electricians and the control group. The average value of all stressors in the electricians is high and a large number (14) of different stressors have higher values than the average value of all the stressors. The subjective assessment of work ability in relation to physical and mental requirements is statistically significantly worse in electricians than in control group. More than half of electricians went on sick leave (mostly short leaves) during the previous year.

CONCLUSION Occupational stress significantly affects work ability of electricians. Values of WAI score are statistically significantly higher in electricians, and values of stressors are equal in relation to WAI score categories. Correlation analysis has shown there is a correlation between age, URS and ERS with individual stressors. 

Evaluation of population health condition is a basic mode of collecting health condition and health needs data of a population. Evaluation of population health condition is a base of contemporary health care and health service as well as health improvement and further health system development. In order to gain information on all (physical, psychological and social) health aspects, one has to go beyond health care system and consider objective health condition indicators gained by routine health statistics along with subjective information for creation an image of health condition, that is to say data collected from citizens themselves. This is significantly important when health condition data are sparse, as this is the case with health marginalized groups such as refugees and displaced persons. Value of data collected in this way is in the fact that they refer to determinants defining health, such as social-economical status, life style, education, employment, quality and availability of health care. The aims of this research is to establish how refugees, housed in refuge camps in the North Kosovo and Metohija, evaluate their health and what are the most common health problems of this population. The research was undertaken as a study of a standard representative sample of the adult refugees housed in the refuge camps in the North Kosovo and Metohija. It involved 109 surveyed people. The questionnaire, used for Health Examination in the Republic of Serbia adapted to local conditions, was utilized as a research instrument. The data were processed by descriptive statistics methods 2 and ÷ test was used in the means of data analyzing. More than a half of the surveyed (55.1%) answered that their health condition was good and very good. There is a great difference in health self-evaluating regarding age, marital status, education, the year when they arrived to current domicile. Less than two thirds (65.2%) of the surveyed in the refuge camps in North Kosovo and Metohija claimed that they suffer from some mentioned chronic illnesses. 

One of aims of health surveys is comparison helth status of residents on different territories. Comparative analysis оf health surveys in five countries: (England, USA, Ireland, Canada and Hungary) and establish opportunities for comparison health status of residents in different country. Will be doing comparative analysis of results from health surveys in five quoted country. First of all, will be doing comparison of methods and derived results. Specially, will be notice on determinants of health which are applied in surveys. Methodology which was used is, mainly, similar in all country. Its health state like a best describes residents of USA. There are most smokers among Hungarians (30,5%) and least of all among Americans (17%). There are most obeses among residents of England (23,1%) and least of all among Canadians (15%). Most Americans and Hungarians (85%) visited general practitioners in recent year. Questions about limited mobility, depression, mental health, cardiovascular diseases, diabetes, blood pressure, fisical activity, mammography, prescribe medicine, estimation quality of health care service and satisfaction with health care service there isn't in most of surveys. We can conclude that the methodology, which was used in surveys, is mainly similar. There are, obviously, variances in wording questions, respecting in determinants of health wich are exploratives in questionnaires. In order to escape these variances, one of the solution would have been using standardized questionnaires, which will be using in future surveys in all country.

Search for objective indicators of health state of the population is essential public health issue. First serious attempt of health evaluation of the population were observed in the end of 18. and beginning of the 19. century. In this period of time, description of health population was mostly based on indicators which were based on data of numbers of death. Later, because of significant decrease of infectious disease and improvement of life and work conditions comes to an extension of average life span. Also, comes to a change of conceptualization of health. As a result of all this changes it has been noticed need for consideration of other aspects of health. As a outcome, indicators of disease, disability and non-biological indicators of health (as a approach to health service, quality of health protection, condition of living, life style factors and environment factors) are more and more necessary for documentation of human capacity for physical, mental and social functioning as a objective analysis of health state. To get all the information of all aspects of health which can not be get from health statistics routine data, was started with examination of population health trough interview, respectively polling out representative population sample. Aim of this studies is to get basic information about population health, in manner to supplement the picture of population states, identify health problems and health needs, to get the picture of representations of risk factors among population; to get the picture of health service utility; to find out health disparity among different countries and inside the country, among different population groups; to follow the change of health states during the time; to follow achievement in health strategy; to insure data for people which are creating health politics, in manner to coordinate theirs politics, strategy and programs. This kind of study is taking place every year in many countries and in others periodically. In our country this kind of studies were done during the year of 2000. and 2006
